  • TF/QB/SMK 78 CO2 Air Rifle

    TF78 Air Rifle
    AKA Qb78 or the SMK78

    ( Edited 14/9/13)

    For those who do not know the TF78 is a very inexpensive air rifle, made in China and is a copy of an old Crossman model. Being Chinese it is heavy and built very solid. Chinese workmanship also being what it is the 78 range of air rifles really can use some tuning.

    These air rifles can be used, when altered, to use either CO2 as its propellant or PCP...but not both at the same time. To actually shoot as a PCP the air rifle does need to be modded.

    At the moment of writing only one place seems to stock the TF78 ( as it is called in the ad) and that is:

    http://buygunsaustralia.com.au/guns.php?make=Tech%20Force

    The company is Hi Power and its run by Jeff, who can usually be contacted here, on this site.

    You Tube has heaps and heaps of videos on how the air rifle can be tuned. Some of them can be found here:

    http://www.youtube.com/user/ArcherAirguns

    or you can look here:

    http://www.youtube.com/user/CompassecoAirguns

    Neither of these places will sell directly to you. They do not sell or ship to Australia

    The rifles can be bulked fill by the use of adapters from here:

    http://www.bryanandac.com/Bulkair.htm

    who do deal with Australia

    To bulk fill you will either need to rent a CO2 tank from someone like CIG or buy your own on an exchange basis from a brew shop like Brewmaster. In the long term, and if you shoot a lot, then bulk filling is inexpensive shooting. You will need to buy a fill station and bits and bobs from Ebay as well. Any hassles, just PM me.

    If you are not going down the bulk fill path you can get your CO2 from:

    http://finewhip.cart.net.au/store/co2/12g-co2-cartridges/

    Should you decide that you want to upgrade your air rifle and need new seals, well they come from:

    http://www.woodfield-gcp.co.uk/

    The TF78 air rifle has facilities for an air rifle scope. I have found a good place to buy these on a budget is:

    http://www.riflesa.asn.au/price_lists/scopes.htm

    but you can buy something like this as well:

    http://www.ausarms.c...hp?subcat_id=13

    It all depends on your budget. Please note that the scope does not have be air rifle rated as it is an air rifle with little or no recoil and behaves much like a normal rifle.

    All air rifles shoot pellets in different ways. It is best to find what suits your air rifle and stick to it a good place for pellets is:

    http://www.acme-firearms.com.au/ammunition/haendler-natermann-air-pellets.html

    But you may just do as ell with any cheap pellets from your LGS. That is something you will need to find out for yourself and also will depend on what you wish to accept in the way of accuracy.

    If you have a 78, well great. If you want to fiddle by yourself, thats fine too. Things are forgiving. A link to an exploded parts diagram is:

    http://ukchineseairgunforum.myfreeforum.org/about5244.html&sid=3dd7d106bf96167feae597e2f057877a

    This is the result of a search and lots and lots of pictures are available.

    The final link is to that of another chat site, or forum site and that is:

    http://ukchineseairgunforum.myfreeforum.org/forum4.php

    Its a great site to visit and has more information about the 78 than you could ever think possible. You do have to be a member to use the site, but its free...just introduce yourself after signing up and you will be pointed in the best direction if you have any inquiries.

    So they choices you have to make are great and varied. This little page here is just a beginning point. I have, I believe, pointed out heaps of places from which you can discover what the air rifle is capable of.

    So if you get either the .177 version or the .22 version you have a great base from which to begin to understand this little gem of an air rifle. The rest is left to you and your imagination.

    Hi...

    Just another add on for my TF78 which basically turns it into a TF79, but uses paintball bottle instead of an 88gm cylinder.

    The adapter is called a drop block and screws onto the existing air/CO2 tube on the rifle, then drops, or offsets, to give clearance under the barrel.

    All you need do to install is just remove the old end cap and slide the new one in. The end cap on the drop block is placed so that all you do is tighten it up. I did this and I also put a little blue Loctite on it so it wouldnt work loose.

    This is a drop block, well several with several views

    The other side of the Drop Block is where you screw in the paintball bottle. You really need something a little smaller than I have. I have just 9oz bottles, and they do not have on/off valves. This means I have to use another adapter that allows on/off of the bottle and the CO2. This means length. The 9oz CO2 bottle actually ends past the end of the barrel and also adds weight. It makes the rifle too end heavy. I would suggest getting a couple of 4oz bottles with in-built on off valves. With this you could hunt all day with little issues. For aesthetic reasons you could get some type of extension as well for the barrel. Its a personal thing.

    This is the drop block fitted to the rifle, with a bottle aside so you can get the idea:

    The air rifle can go where you want it to go now without ever worrying about gas.

    I have been fiddling all morning ( while she who makes my mind up for me was out shopping) and i have fallen in love with it.

    Hi Again

    Just thought it was time to add a bit of a shoe string to show whats going on with the TF78. So with 850 psi showing on the dial I shot the following

    533
    540
    531
    541
    541

    or an average of 537.2 at 10 degree C. It gives a spread of 10fps.

    This gives just under 10 fpe. Not bad at all. This was using Gamo Pro Magnum 5.5 Cal and 15.43grains.

    Let me talk a little about one of the characteristics of CO2. AS the temperature gets warmer the energy that Co2 can deliver gets greater. So at 10 degrees C there is plenty of room to improve as the weather gets warmer.

    So lets compare that with the shoe string from another air rifle, The AR20. This is a target rifle that should be consistent, so one would expect a much closer spread.Like all dedicated target rifles it is .177

    533
    568
    552
    565
    544

    an average of 552 fps or 5.4 FPE

    Amazingly that is an unexpected spread of 35 fps! How ever this rifle is to be shot at a range of 10m so its spread is acceptable. The weather is of no concern as the AR20 is PCP and was fired from a 300bar full tank.

    Even though this is not a hunting rifle it is ok to kill paper at 10m and birds but not anything bigger.

    The price of the AR 20 is near $1000, the price of the modded TF78 as it stands is $327.

    Hi...

    MY barrel extension/ air stripper arrived today, packaged nicely and safely, and its great. It fits very very snugly on the barrel and is also held in place by a discretely place by a hex grub screw.

    the TF78 was shorter that the overall length of the air tank and looked terrible. I was unable to find, and am still looking, some 4 oz CO2 paintball tanks to stop this. An email or two with Matt and he solved the whole thing for me. He listened to what I wanted, saw what I needed and then drew up plans of what would do the job. Unreal service. Worth every cent.

    Thanks for this write up Paul. I am about to purchase an air rifle to knock some myna birds over with as Im sick of using my .22cal rifle. I was looking at the Crossman 1077 but these rifles appear much nicer and have some tunability it seems. My PTA is going in on Monday so hopefully I can add some of my exploits with the TF78 later on.

    Cheers,
    Paul

      A 1077 is a bit short on power for pests. These will do it, as will a nicely tuned springer

      Hi...

      Yes eXile they are really good from scratch...and then you can fiddle. I have fiddled with mine so much it is now like some experimental machine.

      If you get sick of CO2 in the future and want to go PCP, well it doesnt take much to do that conversion either.

      The TF/QB format is very, very flexible.

    Gents,

    If you are after TF78 we can offer Crosman 2250 XE which is a parent model. That rifle comes packaged with a scope for $600.00. Since it is a Crosman package we will not be breaking it.

      Are these on a Cat A/B license or are they stupidly relegated to a Cat H?

      Hi Oleg

      No doubting this the parent rifle for the TF/QB/SMK 78 range but its not really the same. This little rifle is not really as adaptable as the chinese version. At $600 its not far off being over priced for a CO2 air rifle. $600 can be spent on many other things...Springer or PCP. Who really wants to play around with $600 rifle when a cheaper rifle can do the job.

      The 78 is a cheap no nonsense air rifle that is forgiving, well support in the after market, There are dedicated forums, specialist on line shops etc. that cater for the needs of the 78 owner. Plenty of owner/builder/specialist spares makers.

      Paul

      Yes, it is an alternative and I, as a CO2 lover,

      You have TF78s in stock?

  • #5
    Im still working on a steady supply of QB78 guns. There is a company now importing the QB guns direct from China into Australia, which means I no longer have to source from the US. At the moment I don't have any great news in regard stock, I have been chasing the importer for quite some time and have only received a reply today. Unfortunatley for CO2 lovers it would seem they have only concentrated on the springers. I have asked specifically for the CO2 guns, but if they don't have any on this shipment, ( which they told me just cleared customs, and likely to be very limited CO2 ) then we will have to wait till they re order, which could take ages. I have told them if they don't pull their finger out I will begin importing from the US again, so all I can ask is for a little patience and hopefully we will have these great guns available again in the not too distant future.

    Once a steady supply is established we can then offer again, the upgrade kits and possibly the multi shot version I developed. I apologize for the inconvenience, but at this time my hands are tied, id like to do the right thing and buy from the guys importing into OZ, but if they keep stuffing me around ill have to find an alternative.

    cheers

      Hi Jeff, any news on the QB78 supply yet? I really want one but if something doesnt eventuate soon I will just have to settle for a 1077..

      Thanks,
      Paul

    No news im afraid paul. I may have to bring some in from the US again but I fear the price will increase to about $260 with current exchange rates. Would you guys still be interested?

      Hi....

      You might like to read this reply I got from HPA.

      I asked them before there shipment left to order me C02 guns, I was happy to order 50 to 100 given a good price. They ignored that request and brought in the springers. I am waiting on a response from them, otherwise I will again look at Archer for supply, but it wont be till the new year, I just have too much to do in the next 2 months to add QB's onto that. I have even set back the Parker Hale guns till next year also . So if your happy to wait for a few months then I may have some guns available, either from SAG or US, it doesn't worry me either way.I do appreciate the good word you have pushed for me. Ill try my best to get you a 79 ASAP.

      The 78 was well worth the wait and the 79 will be better than the 78....so it is going to be a waiting game. Perhaps the more people who want one the quicker they will come.

      I have noticed on Used Guns that Simpson Sports in Port Kembla have some very nice Chinese springers...but I am going to hold out for a 79. I just hope that HPA brings them in...I enjoy dealing with Jeff and really do not want to deal with some one as far off as Port Kembla that I have not dealt with.

      Paul

    Hi...

    So its not too far off now that my QB/TF 79 air rifle will be landing at Simpsons Sports in Port Kembla NSW and the time has come to start thinking about what I am going to do with it.

    Thanks to the people here, the Chinese air gun website and You Tube i have dangerously enough knowledge to modify these gems...but apart from a little fettle and a drop block to ensure thats the CO2 cylinder doesn't touch the barrel I cannot see me doing much more ( though a HPA/PCP conversion still swirls around in my head)

    Due to some really bad file-keeping i am having hassles trying to source the part...but someone appears to have come to my rescue....

    More info and pics as they come to hand.....and do not forgot to pre-order your 78 or 79 from Simpsons.....and feel free to mention my name....I hassle the guy enough for him to put the price up on you......
